Ring lock guard for a ring binder

In a binder ring metal holding hole punched sheets of paper and the like, the ring metal including a plurality of binder rings each of which is formed by a pair of binder ring halves, and movable frames to which one end of each ring half is attached for movement of the frames to open and close the binder rings, the improvement comprising:

• a ring guard removably installable over each binder ring, when the binder rings are closed, and covering at least a portion of each ring half of each binder ring including a junction where outer ends of the ring halves for the respective binder rings meet when the binder is closed, each ring guard securely gripping its associated binder ring and preventing a gap from opening between the ring halves of the binder ring when the binder is subjected to a force which would otherwise cause a gap to form between the outer ends of the ring halves of a binder ring and the paper stored in the binder to spill out or be damaged.
